• B (Boron)


  Mitotic activity for root development
• Ca (Calcium)


  Structural component of the cell wall and membrane
• Cl (Chlorine)


  Water splitting of PSII; stomatal opening regulation
• Cu (Copper)


  Co-factor for metalloproteins and enzymes
• Fe (Iron)


  Regulatory component of proteins and metabolites
• Mg (Magnesium)


  Chlorophyll Synthesis
• Mn (Manganese)


  Photodestruction of chlorophyll and chloroplast structure
• Mo (Molybdenum)


  Enzyme activation; chlorophyll synthesis
• Ni (Nickel)


  Root nodule growth
• N (Nitrogen)


  General plant growth of roots, stem and leaf

  Assimilation of redox rxns
• Zn (Zinc)

  Enzymatic fx and reactivity; stem elongation; protein and starch synthesis
• Abscisic Acid (ABA)


  Seed germination, leaf senescence, stomatal aperture, adaptation to environmental stress
• Auxin


  Stimulates cell elongation; growth of pre-existing roots
• Brassinosteroids (BR)


  Abiotic stress responses; seed germination; reproductive development; regulates plant defenses
• Cytokinin (CK)


  Seed development; cell differentiation; chloroplast formation
• Ethylene (ET)


  Defense from necrotrophic pathogens; fruit ripening
• Gibberellins (GA)


  Response to nutritional limitation
• Jasmonic Acid (JA)


  Defense from necrotrophic pathogens and herbivore insects; tendril coiling, leaf senescence, fruit ripening, tuber formation, stomatal opening
• Salicylic Acid (SA)


  Defense response from biotrophic and hemi-biotrophic pathogens
